Geoid models

Geoid models are used in Hydromagic to calculate tides, or the height of the bottom of a river or lake using a RTK receiver and a vertical datum. By default, the installation package of Eye4Software Hydromagic only contains a small selection of geoid models.

We only ship a selection of geoids with the software, because the package would be several hundreds of megabytes when we decide to include all these files. This page allows you to find and download the required geoid model in the ".GEO" format used by Hydromagic. The video below shows how to import the files into Hydromagic:

All .GEO files are converted directly from the geoid files downloaded from official sources.
We are not responsible for the contents of these files, you will use them at your own risk.
